This page summarizes what is publicly known and publicly stated about the proposed development on Rifle Range Road, in Marshfield, Missouri. Where information has been provided by the developer or the County Commission and has not been independently verified, that limitation is noted directly.
The development is publicly associated with Lumon Solutions Marshfield, LLC. The company's public LinkedIn page describes Lumon as developing a Tier III, AI-ready facility for high-density workloads and next-generation compute, and lists the industry as "Data Infrastructure and Analytics."
According to information provided by Lumon Solutions to the Webster County Commission in early May 2026, as published in the Commission's official statement and reported by the Marshfield Mail, the project was described as a "small-scale high-performance computing facility" on a five-acre site, with building dimensions of approximately 70 by 200 feet, closed-loop cooling, and water usage estimated at a few hundred gallons per month.
In a Facebook post on May 13, 2026, reported by the Springfield Daily Citizen, Lumon Solutions revised some specifics. The company described the project as a "high-performance computing research facility" — not a data center — and stated that the current plan consists of several small modular buildings totaling approximately 7,000 square feet, configured as eight modular units of roughly 600 square feet each. According to Ozarks First's coverage of the same post, the company also stated water usage of less than 5 gallons per day, no wastewater, no chemical discharge, noise comparable to a standard HVAC system, use of existing available electrical capacity from a nearby substation with no upgrades required from Webster Electric Co-Op customers, and creation of more than a dozen jobs. The developer has separately stated, as reported by KY3, that a well drilled approximately 500 feet deep will supply the facility.
These figures are as stated by Lumon Solutions. They have not been independently verified through engineering studies, environmental modeling, peer review, or third-party site inspection.
According to the Springfield Daily Citizen, a special portion of the Webster County Commission meeting drew approximately 800 (in-person) attendees to the Marshfield High School auditorium on May 11, 2026, filling the main floor, upper-level seats, and overflowing into the lobby. The two-hour information session concluded without concrete next steps.
KY3 reported that Commissioners have retained the law firm Carnahan Evans to review what authority the county may have under state statute. Northern District Commissioner, Dale Fraker, told attendees that because Webster County does not have Planning and Zoning, county oversight is limited, and that Commissioners want more information on environmental impacts and have not ruled out additional public meetings. Per Daily Citizen reporting, many residents present at the meeting called on the Commission to adopt a one-year Moratorium to halt the project, pending environmental and health studies.
Site work on Rifle Range Road continues.
On May 13, 2026 — two days after the public meeting — Lumon Solutions posted a public statement on Facebook. As reported by the Springfield Daily Citizen, the company stated it will proceed with the project and that it believes it is acting within its legal rights to do so, on the grounds that Webster County does not have Planning and Zoning regulations that prohibit this type of development. Ozarks First reported that the company characterized public discussion as containing "misinformation, fear, political propaganda and verbal attacks" and stated it has not seen any factual study, engineering report, environmental report, or scientific finding showing the facility creates a public health danger.
As stated in the Webster County Commission's official release, Lumon Solutions has not requested any tax abatement or economic development incentives from the county.
Per Springfield Daily Citizen reporting, the three-member Webster County Commission consists of Paul Ipock, Presiding Commissioner; Dale Fraker, Northern District Commissioner; and Randy Owens, Southern District Commissioner. Stanley Whitehurst serves as Webster County Clerk.
In its official statement, the Commission stated it was initially unaware of the development before it became public. It has since been in contact with the developer and, as noted above, has retained outside counsel.
The following impacts have not been independently verified through engineering studies, environmental modeling, peer review, or third-party site inspection:
